Is it weird that I'm not interested?

I'm 19 and have never had a boyfriend or even gone on a date. This summer I've been working in construction, and I'm the only girl on site. One of the guys made a comment recently that I could have any guy I wanted. I told him that I didn't care and he was giving me a hard time about it. I love my life, and right now I just don't want or need a guy. Is that weird?
